HENRY K. BURNETT, OF POUGHKEEPSIE, NEW YORK.

IMPROVEMENT lN HARVESTERS.

Specification forming part of Letters Patent No. 80,272, dated July 28, 1868.

To all whom it may concern:

Be it known that I, HENRY K. BURNETT, of Poughkeepsie, in the county of Dutchess and State of New York, have invented and made a certain new and useful Improvement in Mowing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is a perspective View of the said mowingmachine. Fig. 2 is a plan of the same, with the tongue, seat, and part of the frame removed; and Fig. 3 is an elevation of the ratchet-wheel and spring-pawl upon the axle.

Similar marks of reference denote the same parts.

In my mowing-machine, a reciprocating movement is given to the cutter-bar by a vibrating leverarm between zigzag cams, that face each -other, and are revolved by gearing to the axle of the main wheel. The shoe at the inner end of the finger-bar runs upon a wheel, and the finger-bar is hinged to the same in such a manner that the said finger-bar can be turned over and lie parallel, or nearly so, to the face of the wheel.

In the drawing, A A are the main wheels upon the axle b, but loose thereon, and M M are ratchet-wheels fastened on the axle b; and P is a pawl on the hub-plate N, acted upon by the spring 0, (see Fig. 3,) so that the machinemay be turned around or backed, as usual, but that the axle b will be rotated when the machine is drawn forward.

Upon the axle bis a wheel, B, gearing into the pinion O, the shaft of which is supported in the frame d, and upon said shaft are the cylindrical cams D 1), with scalloped edges, sitting opposite to each other, the undulation on one cam coming opposite the projection upon the other, so that a zigzag opening is produced, and in this lies the roller E upon the arm U that has its fulcrum in the standard T. The distance between the cams D D is such that the arm U lies freely between said cams, and is rapidly vibrated by their action upon the roller E.

The outer end of the arm U is supported by a frictionroller, F, against the under side of the frame d.

G is the pitman, extending from the vibratin g arm U to the cutter-bar h and cutters 'i.

H is the finger-bar having the fingers L L. S is a shoe and track-clearer at the outer end of the finger-bar H, as usual.

The inner end of the finger -bar H rests upon and is bolted to the right-angle bar K, the forward part of which is united .to the shoe R by means of a joint formed by the flanges or cars Y Y and pin T. The shoe R runs upon the wheel R, and the back end of the shoe R is connected by the joint ears V V and pin W to the arm X that extends below the frame (I, andthe bar K is united at its back end by an eye to an eye on the end of (tehe pin W, so as to form a swivel-joint, as at The shoe R and cutter-bar move upon the joint V W to accomodate inequalities in the surface of the ground.

The pitman G is formed with a joint at e that connects the same with the outer end of the arm U, and the joint I to the cutter-bar h is provided with a removable pin, which is to be taken out, and also the pin J, when the finger -bar is swung around upon the joint Q and laid into the crotch bar f that ex tends from the back part of the frame (1, and supports said finger-bar at the side of the wheel A.

The shoe B and finger-bar H may be raised, if desired, by the lever-segment and chain 9, Fig. l. The brace I, extending from the frame (1 to the shoe R, steadies that-shoe, and a slot in said brace, at the point where it is bolted to the frame, allows the shoe R to be lifted.

What I claim, and desire to secure by Letters Patent, is j p 1. The cams D D rotated by the gearing B O, in combination with the arm U, roller E, and jointed pitman Gr, connecting the arm U to the cutter-bar a, substantially as set forth.

2. The bar K at the end of the finger-bar H, and jointed at Q to the shoe R and arm X, as and for the purposes set forth.

3. The shoe R jointed to the arm X, in combination with the slotted brace I, fingerbar H, and cutters 11, arranged and operating as and for the purposes set forth.
